Effect of acute restraint stress for 1 h on CRH hnRNA levels in the PVN of naive rats (B) or 24 h after the last restraint in rats subjected to 1h repeated restraint for 14 days (D). Basal CRH hnRNA were almost undetectable in both naïve rats (A) and repeatedly restrained rats 24 h after the last episode (C). Darkfield photographs were taken through the medial parvocellular subdivision of the PVN (MP). 3rd V, Third ventricle; RR × 14, repeated restraint, 1h daily for 14 days.
